UNVENTED (VENT-FREE) NATURAL GAS FIREPLACE
PRODUCT
FEATURES
OPERATION
This vent-free fireplace is clean burning. It
requires no outside venting. There is no heat
loss out a vent or up a chimney. Heat is
generated by both realistic flames and glowing embers. The fireplace requires no electricity making it ideal for emergency backup heat.
SAFETY FEATURES
This fireplace has a pilot with an Oxygen
Depletion Sensor Shutoff System (ODS).
The ODS/pilot is a required feature for ventfree room heaters. The ODS system protects
against oxygen depletion and any interruption in the fuel supply. If either occurs, the
ODS shuts off gas flow to the burner, turning the fireplace off. An internal regulator
controls fluctuations in your gas pressure.
PIEZO IGNITION SYSTEM
This fireplace has a piezo ignitor. This system requires no matches, batteries, or other
sources to light fireplace.
THERMOSTAT CONTROL
(CGFP28NT)
These fireplaces have a thermostat sensing
bulb and a control valve. The thermostat
controls the heat output and flame height.
This maintains a consistent room temperature. Even the lowest setting provides realistic flames and glowing embers from two
burners. Selecting higher comfort settings
allows the fireplace to run longer, producing greater heat output. At lower comfort
settings, the fireplace will run less. This
results in increased heating comfort. This
can also result in lower gas bills. An optional thermostatically (GA3650T) or manually (GA3750) controlled blower is available (see Accessories, page 25).
VARIABLE MANUAL
CONTROL (CGFP28N)
These fireplaces have a variable manual control valve which allows the user to choose the
heat setting that best suits his needs. Any
setting between low and high may be selected
by simply turning the control knob. An optional manually controlled blower (GA3750)
is available (see Accessories, page 25).
AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This heater shall
not be installed in a confined space
or unusually tight construction
unless provisions are provided for
adequate combustion and ventilation air. Read the following instructions to insure proper fresh air for
this and other fuel-burning appliances in your home.
Today’s homes are built more energy efficient than ever. New materials, increased
insulation, and new construction methods
help reduce heat loss in homes. Home owners
weather strip and caulk around windows and
doors to keep the cold air out and the warm air
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper combustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide adequate fresh air for these appliances. This
will insure proper venting of vented fuelburning appliances.
PROVIDING ADEQUATE
VENTILATION
The following are excerpts from National
Fuel Gas Code. NFPA 54/ANS Z223.1, Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 4 through 6 will
help you classify your space and provide
adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for
combustion and ventilation. However, in
buildings of unusually tight construction,
you must provide additional fresh air.
4
Unusually tight construction is defined as construction where:
a. walls and ceilings exposed to the
outside atmosphere have a continuous water vapor retarder with
a rating of one perm (6x10
pa-sec-m2) or less with openings
gasketed or sealed
b. weather stripping has been added
on openable windows and doors
and
c. caulking or sealants are applied to
areas such as joints around window and door frames, between
sole plates and floors, between
wall-ceiling joints, between wall
panels, at penetrations for plumbing, electrical, and gas lines, and
at other openings.
If your home meets all of the three
criteria above, you must provide additional fresh air. See
From Outdoors
If your home does not meet all of the
three criteria above, proceed to

Confined Space and Unconfined
Space
The National Fuel Gas Code ANS Z2123.1,
1992 Section 5.3) defines a confined space
as a space whose volume is less than 50
cubic feet per 1,000 Btu per hour (4.8 m3 per
kw) of the aggregate input rating of all
appliances installed in that space and an
unconfined space as a space whose volume
is not less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3 per kw) of the aggregate
input rating of all appliances installed in that
space. Rooms communicating directly with
the space in which the appliances are installed*, through openings not furnished
with doors, are considered a part of the
unconfined space.
This heater shall not be installed in a confined space or unusually tight construction
unless provisions are provided for adequate
combustion and ventilation air.
* Adjoining rooms are communicating only
if there are doorless passageways or ventilation grills between them.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION
Determining if You Have a Confined or Unconfined Space
Use this work sheet to determine if you have a confined or unconfined space.
Space: Includes the room in which you will install fireplace plus any adjoining rooms with doorless passageways or ventilation grills
between the rooms.
1. Determine the volume of the space (length x width x height).
Length x Width x Height = _________________cu. ft. (volume of space)
Example:
If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total vol ume of
the space.
2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.
_________________ (volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)
Example:
3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free fireplace ___________________Btu/Hr
Gas water heater* ___________________Btu/Hr
Gas furnace ___________________Btu/Hr
Vented gas heater ___________________Btu/Hr
Gas fireplace logs ___________________Btu/Hr
Other gas appliances*+ ___________________Btu/Hr
Total = ___________________Btu/Hr
* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.
4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
_________________ Btu/Hr (maximum the space can support)
_________________ Btu/Hr (actual amount of Btu/Hr used)
Example:
The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.
You must provide additional fresh air. Your options are as follows:
A. Rework work sheet, adding the space of an adjoining room. If the extra space provides an unconf ined space, remov e door to adjoin-
ing room or add ventilation grills between rooms. See Ventilation Air from Inside Building, page 6.
B. Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 6.
C. Install a lower Btu/Hr fireplace, if lower Btu/Hr size makes room unconfined.
If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no
additional fresh air ventilation.
Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 cu. ft. (volume of space)
3168 cu. ft. (volume of space) ÷ 50 cu. ft. = 63.3 or 63,300 (maximum Btu/Hr the space can support)
Example:
Gas water heater 40,000 Btu/Hr
Vent-free fireplace + 28,000 Btu/Hr
Total = 68,000 Btu/Hr
63,300 Btu/Hr (maximum the space can support)
68,000 Btu/Hr (actual amount of Btu/Hr used)
WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space
or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of
the methods described in the

will start when the thermostat senses a sufficient increase in firebox temperature.
Note:
Your gas logs and thermostat blower
will not turn on and off at the same time. The
fireplace may run for several minutes before
the blower turns on. After the heater modulates to the pilot position, the blower will
continue to run. The blower will shut off
after the firebox temperature decreases.
Note:
It is safe to operate fireplace with
blower turned off. However, the blower helps
distribute heated air from the fireplace.
Note:
Periodically check the louvers of the
firebox and remove any dust, dirt, or other
obstructions.
